  • I watched it, now YouTube please stop recommending it

  • I watched this and it still gets recommended to me whut

  • Can you cast Obsidian? No. You can't. Saved you 14m.

  • Hey Mate, Lead crystal glass artist Adam Norman Jenkins here. A few points that might help you in future work. First up, we coat all our bricks and the inside of our kilns with a thing called "High Fire Kiln Wash"...a company called Paragon makes a good one that is specific for glass, if your crucible breaks and glass comes pours into your kiln the kiln wash protects your valuable kiln (I regularly have high temparture lead crystal glass flow all through my kiln just because I'm too lazy to measure and cut my glass properly). Second point, you're always going to have problems sand casting glass which is why glass sculptors generally don't. What we do is create a multilayer refactory mould (each layer has a different chemical composition because it has different goals)...we put the mould AND crucible into the kiln at the same time (it's called a gravity load crucible), not only that, we have to consider sprue, risers, feeders and gates when making our mould. The reason we put it all in together is annealing. When casting glass you can't just use an annealing kiln like blowers use. Their glass is a special composition and is very thin....cast glass is generally lead crystal (or obsidian) and is thick as heck so it takes a LONG time to move between stages. A small-ish 25 cm piece sits in the kiln between 400 & 850 celcius FOR 5 DAYS! Your obsidian is brittle because you didn't anneal properly or for long enough or at the right temperature. If you put a strong backlight under it and look at it with a polarising filter (grab on from an old LCD monitor) you will see rainbow colours in your obsidian, these are stresses that have been captured into the glass...if I see rainbow stress in a piece it goes in the bin (or actually, back in the kiln to be re-cast into something else). Stresses in glass are an odd thing, you never know when they're going to break...a sculpture can be sitting happily one someones shelf for 5 years and then a wind will blow across it the wrong way and it will shatter into a million pieces. So you can't sell anything with stresses in it and, realistically, if you have stresses you have a problem with your process. Hope that helps, hit me up if you need any more info for any future casts of glass or glass-like objects. If anyone wants me to do a video of what I'm talking about let me know. Cheers, Adam

  • yeah bro just download the new Minecraft mod

  • Poor pewds editing his own video

  • Next: Can you melt wool and cast it into a sword??

  • "Is it possible to melt Obsidian?" Yes but I don't have the equipment to do it so I'll just smash it, mix it with a lot of other stuff that melts and incorporate it..."It's arguable to call this obsidian" It's just not.

  • You could have done it in one try if you used a diamond pickaxe

  • Short answer:

  • 1ik 

    There i watched it, please stop recommending this to me for the love of god

  • Bro....you and your cat are gonna get lung cancer. Please wear a mask and keep your cat out of your workshop.

  • What minecraft mod is this

  • Try mixing water with lava

  • You've seen those videos that give a sense of satisfaction as you watch? Yeah this video was the antithesis of that. Lol.

  • dude i feel so bad for him, he did so much.

  • Obsidian is a natural volcanic glass that is a very thick fluid. High silicon lavas tend to be very explosive because of the viscosity associated with that type of lava. This type of lava chemistry tends to form rocks like rhyolite/granite. Typically, obsidian can flow only because it is a superheated lava that is 25-30% hotter than a typical basaltic lava (1300-1400 C. vs 1000-1100 C.). Even at that temperature, it doesn’t flow well. That higher temperature is probably much hotter than your kiln temperature. Low silicon lavas are more fluid and tend to be cooler in lava temperature range (like basalt on Hawaii). I suppose adding a flux would change the composition and therefore make it something more like manmade glass instead of true obsidian (why it flows easily). Still an interesting video. Thanks!! I’ve heard (but don’t know for sure) that some flint knappers bake stones like solid basalt to make them more brittle—enabling them to knap an edge onto rocks that are not obsidian.
